Sunstone and Hibschite Physical Properties

Sunstone and Hibschite Chemical Formula

While comparing Sunstone and Hibschite physical properties, the important data you should know is its chemical composition. Since chemical formula defines the molecular structure of the crystal, most of the physical properties like color, tenacity, solubility are governed by Sunstone and Hibschite chemical formula.

• Chemical formula of Sunstone- Microcline: KAlSi₃O₈ Oligoclase: (Na,Ca)Al_1-2Si_3-2O₈
• Chemical formula of Hibschite- Ca 3Al 2(SiO 4) 3-x(OH) 4x (x=0.2 to 1.5)Anthony et al , Handbook of mineralogy (2001)

Sunstone and Hibschite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Sunstone and Hibschite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Sunstone and Hibschite Optical Properties during the identification of gemstone. Specific gravity of Sunstone is 3.05-3.08 whereas that of Hibschite is 3.05-3.08.
